The production of most fruiting vegetables such as tomatoes and cucumbers depends more on maturity of the plants than day length
. They're sometimes referred to as day-neutral.
Previous calculations for the day length
fell between 10 hours, 36 minutes and 10 hours, 48 minutes, but scientists could not give an exact number.
The findings suggest that using light treatment in the late third trimester when seasonal day length

Salinity was not significantly correlated with day length
and water temperature.
We tested using general linear models (GLM) with IBM SPSS Statistics 22 if 1) age of birds, 2) sex, 3) breeding method and 4) day length
influenced daily ranges, distance travelled per hour and number of times capercaillies fed per h.
Birds such as blackbirds and blue tits are behaving much as normal, as day length
is an important factor in when they breed, while sightings of insects including ladybirds and redtailed bumblebees are also around average.
"But long-distance migratory birds, for example, time their migration based on day length
in their winter range.
Some edible plants are referred to as "day-length sensitive," although day length

The days are longer (day length
reached 14 hours today), the sun is stronger and general conditions are such that a prime-growing season is upon us.
